Testing the Addition of the Chemotherapy Drug Lomustine (Gleostine) to the Usual Treatment (Temozolomide and Radiation Therapy) for Newly Diagnosed MGMT Methylated Glioblastoma

United States265 participantsStarted 2022-03-28

Plain-language summary

This phase III trial compares the effect of adding lomustine to standard chemotherapy with temozolomide and radiation therapy versus temozolomide and radiation therapy alone in shrinking or stabilizing newly diagnosed MGMT methylated glioblastoma. MGMT methylated tumors are more likely to respond to temozolomide chemotherapy. Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill tumor cells and slow down or stop tumor growth. Lomustine is a chemotherapy drug and in a class of medications called alkylating agents. It damages the cell's DNA and may kill tumor cells. Radiation therapy uses high energy x-ray photons to kill tumor cells and shrink tumors. Adding lomustine to standard chemotherapy with temozolomide and radiation therapy may shrink or stabilize glioblastoma.

Inclusion Criteria: * STEP 1 REGISTRATION: No known IDH mutation. (If tested before step 1 registration, patients known to have IDH mutation in the tumor on local or other testing are ineligible and should not be registered) * STEP 1 REGISTRATION: Availability of formalin-fixed paraffin-embedded (FFPE) tumor tissue block and hematoxylin and eosin (H\&E) stained slide to be sent for central pathology review for confirmation of histology and MGMT promoter methylation status. Note that tissue for central pathology review and central MGMT assessment must be received by the New York University (NYU) Center for Biospecimen Research and Development (CBRD) on or before postoperative calendar day 30. If tissue cannot be received by postoperative calendar day 30, then patients may NOT enroll on this trial as central pathology review will not be complete in time for the patient to start treatment no later than 8 weeks following surgery. Results of central pathology review and central MGMT analysis will generally be completed within 10 business days of receipt of tissue. Results will be entered by the central lab directly into Rave. Note: In the event of an additional tumor resection(s), tissue must be received within 30 days of the most recent resection and the latest resection must have been performed within 30 days after the initial resection. Surgical resection is required; stereotactic biopsy alone is not allowed because it will not provide sufficient tissue for MGMT analysis * STE…
